Every technician holds active SC contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Duncan job.
Our Duncan-based crews target 60-minute on-site response. We don't route your emergency through a regional call center — local dispatch means faster arrival and better outcome.
Xactimate-based scope of work reviewed with you before any equipment is placed. The estimate you approve is the invoice you receive — no hidden line items, no after-the-fact surprises.
Every Water Damage Restoration job in Duncan carries our written satisfaction guarantee. If the result doesn't meet the documented standard, we return and make it right at zero additional cost.
COS Water Damage Restoration's Water Damage Restoration service in Duncan covers the complete recovery process — from the first emergency response through mold prevention, structural drying, and full rebuild.
Speed at this phase directly determines how much is salvageable. Our Duncan crews don't slow down on the way to your property.
Every affected assembly is documented with instrument readings before drying begins.
Industrial LGR dehumidifiers and high-velocity air movers are deployed in calculated configurations based on your Duncan property's materials, square footage, and psychrometric conditions. Daily readings at fixed sensor points document the drying progression until all assemblies reach target equilibrium moisture content.
We don't rebuild over hidden mold risk.
Supplement filing for underpaid Duncan claims is part of the service.
One company, start to finish.

Local crews mean local speed — we know Duncan's roads and we move fast.
No work starts without your written approval of the scope and cost.
Extraction, drying, remediation, and reconstruction proceed under daily monitoring and documented progress reporting. The job isn't complete until final moisture readings confirm success and you've conducted the walkthrough with your project manager.



"Our Duncan business had a roof-to-slab water event on a Thursday night. By Friday morning COS Water Damage Restoration had extracted everything, staged drying equipment, and given me a documented scope I could hand directly to my adjuster. We were operational again the following week. Truly professional."
"The insurance side of a water damage claim is overwhelming. COS Water Damage Restoration's Duncan team handled everything — filed the first notice, attended the adjuster visit, and got us a fair settlement. I didn't make a single insurance phone call myself."

COS Water Damage Restoration was the only one who walked every room with instruments before quoting, explained each line of the estimate, and committed to the timeline in writing.
